Is it really true that I need a licence to program the GIF file format
for my purpose? T remember there was a GIF89a EU include lib for DOS in
the archive which might be just usable for my demands. Is that 'warez'?

I agree in principle here. But JPEG is unusable for graphics. The idea
to use embedded JavsScript is probably better, though one has to fight
with an unusual language (I at least).

It's easy for me to program the kind of graphics I need via graphics.e
under DOS. Is there no similar easy way possible without introducing a
special language?

Mike, thank you anyway for your warnings and ideas, and
have a nice day, Rolf
